Can repro this issue at Android platform on the latest 17.6.12(build 410)(8.0.21&8.0.40).

I have verified this behaves as stated above.

I wonder if the issue is the timing with the await Shell.Current.GoToAsync(".."); right after the SemanticScreenReader.Announce(RecipeName + " recipe added."); call.

If I remove the GoToAsync call, the full announcement is made.

Not sure how manageable this would be, but perhaps adding an async Announce method could be worth trying here:

namespace Microsoft.Maui.Essentials
{
    public static partial class SemanticScreenReader
    {
        public static async Task Announce(string text)
        {
            if (!UIAccessibility.IsVoiceOverRunning)
                return;

            var tcs = new TaskCompletionSource<bool>();

            MainThread.BeginInvokeOnMainThread(async () =>
            {
                await Task.Delay(100);
                UIAccessibility.PostNotification(UIAccessibilityPostNotification.Announcement, new NSString(text));
                // Adding some way of knowing/guessing when the Notification is finished reading?
                tcs.SetResult(true);
            });

            await tcs.Task;
        }
    }
}

Worth noting that there were timing issues with iOS Screenreader here: #3736

There is also an interesting workaround here: https://stackoverflow.com/a/59329208

Perhaps a little tricky but has potential!
